/**

 * Twenty Eleven functions and definitions

 *

 * Sets up the theme and provides some helper functions. Some helper functions

 * are used in the theme as custom template tags. Others are attached to action and

 * filter hooks in WordPress to change core functionality.

 *

 * The first function, terapixel_setup(), sets up the theme by registering support

 * for various features in WordPress, such as post thumbnails, navigation menus, and the like.

 *

 * When using a child theme (see http://codex.wordpress.org/Theme_Development and

 * http://codex.wordpress.org/Child_Themes), you can override certain functions

 * (those wrapped in a function_exists() call) by defining them first in your child theme's

 * functions.php file. The child theme's functions.php file is included before the parent

 * theme's file, so the child theme functions would be used.

 *

 * Functions that are not pluggable (not wrapped in function_exists()) are instead attached

 * to a filter or action hook. The hook can be removed by using remove_action() or

 * remove_filter() and you can attach your own function to the hook.

 *

 * We can remove the parent theme's hook only after it is attached, which means we need to

 * wait until setting up the child theme:

 *

 * <code>

 * add_action( 'after_setup_theme', 'my_child_theme_setup' );

 * function my_child_theme_setup() {

 *     // We are providing our own filter for excerpt_length (or using the unfiltered value)

 *     remove_filter( 'excerpt_length', 'terapixel_excerpt_length' );

 *     ...

 * }

 * </code>

 *

 * For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
